The Invoke method is called in response to receiving an invoke transaction to process transaction proposals. The other interface in the chaincode “shim" APIs is the ChaincodeStubInterface which is used to access and modify the ledger, and to make invocations between chaincodes. In this tutorial, we will demonstrate the
1 Mar 2017 Learn how to develop chaincode using Golang for a blockchain network based on Hyperledger Fabric v0.6. This deep-dive tutorial covers the fundamentals, such as the APIs for interacting with the Fabric, as well as advanced topics like data modeling, access control, and events. Abundant sample code
13 Oct 2016 Next in the series, we'll work with chaincode. Chaincode is usually Go (GoLang) code (alternatively Java code) , deployed into a network of Hyperledger fabric peer nodes that enables interaction with that network's shared ledger. Whenever you 'invoke' a transaction on the network, you are calling a
23 May 2017 This tutorial shows how to develop a Node.js client application to talk to a blockchain network based on Hyperledger Fabric v0.6. It details registration, enrollment, and access control, and provides reusable code for setting up a blockchain network and querying the blockchain.
A collection of expert hyperledger blockchain tutorials that explain how to install Hyperledger dependencies and execute functions such as deploy, invoke and
At the end of this tutorial, you will have constructed a running instance of Hyperledger Fabric business network, as well as deployed, instantiated, and executed chaincode. In addition, our network will have TLS enabled. The tutorial describes the context of fictional "acme.com" company and its three organizations: Org1,
package main import ( "fmt" "github.com/hyperledger/fabric/core/chaincode/shim" pb "github.com/hyperledger/fabric/protos/peer" ) // HeroesServiceChaincode implementation of Chaincode type HeroesServiceChaincode struct { } // Init of the chaincode // This function is
One, from the perspective of an application developer developing a blockchain application/solution entitled Chaincode for Developers, and the other, Chaincode for Operators oriented to the blockchain network operator who is responsible for managing a blockchain network, and who would leverage the Hyperledger Fabric
15 Mar 2017 Blockchain is changing the way business transactions are done on the Internet. In this tutorial, you'll install a blockchain network and run a chaincode smart contract written in the Java language.
This tutorial demonstrates the basic building blocks and functionality necessary to build an elementary Hyperledger fabric chaincode application. You will be incrementally building up to a working chaincode that will be able to create generic assets. Then, you will interact with the chaincode by using the network's API.
